LUTHER/E. JEROME, OF NE7 HAVEN, CONNECTICUT, ASSIGNOR TO THE NEW HAVEN CLOCK COMPANY, OF SAME PLACE.

CLOCK-DIAL.

SPECIFICATION forming part of Letters Patent N0. 241,988, dated lVIay 24, 1881.

Application tiled April 16, 1881.

To all whom t may conce/m:

Be it known that I, LUTHER E. JEROME, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Clock-Dials5 and I do hereby declare thefollowing, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ot' the same, and which said drawings constitute part. oi' this specification, and represent, in-

Figure l, a front view; Fig. 2, a rear view; Fig. 3, a transverse section enlarged.

This'invention relates to an improvemei'it in that class of clock-dials which are provided with a secoiui-haiul, the object being to recess the dial and ornament the margin ot" said recess; and it. consists in cutting'acircularopening through the dial and setting therein a cupshaped smaller dial, the edge ofthe cup molded so as to overlap onto the face ot' the main dial, as more fully hereinafter described.

A represents the main dial, ofthe usual form. At the point where the second-pointer dial is required I cut a circular opening, a., a little is required to be.

B is the seeond-pointer dini, which is struck from sheet metal into cup shape, as seen in Fig. 3, the external diameter of the cup corresponding to the diameter ot' the opening ct through the dial. The edge of the cup is turned outward and so as to overlap onto the i (No model.)

surface oi' the principal dial to cover thejoint between the two. This edge may be molded in any desirable shape to form a margin around the second-dial. This cup-shaped dial produces the best effect to be made from brass and retain that color in contrast with the white ot' the principal dial.. It is secured in place by two or more drops ot' solder on the back side, as at d, Fig. 2.

Sunken second-dials are well known; but they have usually been made by making a depression in the principal dial and then setting n molding around the edge ot' the depression.

By making the seconddial and its margin in one and the sime piece it is more readily prepared than when the graduation and iiguring are required in the depression in the principal dial, and thel second-dial in a single piece is secured in the opening in the principal dial with much greater facility than the detached border-molding can be.

I claim- A clock-dial having an opening made therein for the second-dial, combined with a seconddial havinga molded edge formed in the saine piece with the dial, and so as to set into the opening in the principal dial, the edge ot' the second-dial overlapping onto the surface ot' the principal dial, substantially as described.

L. E. JEROME.
